## Presentation on theme: "BCT 102 Printreading Architect Civil Engineer Reading & Scale Use."— Presentation transcript:

Scaled Drawings Plan drawings to scale allows a visualization of relative room areas and location, house to property location and basic functional design of the plan. Using scaled drawings allows the architect or designer to indicate specific information. Scaled elevations provide a visual image of the entire building and or various section components. Different scales are used for different drawing types.

1/4" to 1' = most common plan scale Architect Scale Notice 1', 3', 5' etc. numbers not present Opposite end 1/8" scale foot numbers

¼" Scale: Inch and odd # feet increments have no numbers. What is the length between arrows ? 7' – 9"

3" = 1' SCALE 3"6"9" 1' Represents 4' from opposite end 1 ½" scale

1 ½” = 1 foot scale What is the length represented ? 1’ – 8” ? 3/8” scale What is the length represented ?7’ – 6”

¾ " to 1' scale common to cabinetry detail drawings ¾ scale 2' – 6" would = ____? On the inch ruler 1 7/8 "

Standard U.S. 12" ruler Full scale 3/32" = 1' scale The architect scale ruler has how many different scales ?11

Civil engineer scale, where 1" = the # of feet listed on the scale

Used most common for large area plan view such as property dimensions or large commercial construction site plans. One inch = 20', the # 2 represents 20'

The # 4 is one inch from "0" represents 40' This increment line represents ? Feet and is ? Inches long 70' 1 ¾" The engineers scale has how many different scales6

Plan Dimensions Most dimensions will be written on the plan. Occasionally a needed dimension will not be available. The appropriate scale will allow the plan reader to measure this dimension. If a written dimension and the scale dimension measured are different, Use the written dimension. Sometimes in the field a carpenter may need to scale a dimension without a scale available. The standard inch rule can be used.

Use the inch ruler as a scale What is this length in 1/4" scale? 14'
